Patented Mar. 8, 1932 UNITED STATES PATENT caries CHARLES E. GLESSNER, OF PORTLAND, OREGON, ASSIGNOR OF ONE-HALF T JULIA H.

BIRKENBEUEL, OF PORTLAND, OREGON ROTATABLE HANGAR FOB LIGHTER-THAN-AIR SHIPS Application filed November 26, 1928. Serial No 321,812.

This invention relates generally to aeronautics, and particularly to means for housing lighterthan-air ships.

The main object of this invention is to make the launching and landing of lighterthan-air ships independent of wind direction.

The second object is to expedite the landing and launching of lighter-than-air craft.

1 The third object is to provide a special form of rotatable hangar.

The fourth object is to reduce the hazard ordinarily accompanying the landing and launching of lighter-than-air craft.

The fifth object is to reduce the amount of man power required in landing and launching lighter-than-air craft.

The sixth object is to provide a hangar for ligl1ter-than-air craft which will be relatively low in first cost and have nothing to get out of order.

These, and other objects, will become more apparent from the specification following as illustrated in the accompanying drawings,

5 in which:

Figure 1 is a plan view of the hangar. Fig I ure 2 is a Vertical section taken along the line 2-2 in Figure 1. Figure 3 is an enlarged section taken through one of the rollers. Figure 4 is a perspective view of the hangar.

Similar numbers of reference refer to similar parts throughout the several views.

Referring in detail to the drawings, there is shown a representative form of hangar having a rounding roof 10 and relatively straight sides 11 and having one end 12 closed which may be provided with openings 13 for the passage of vehicles and pedestrians. The opposite end 14 is normally open for the purpose of allowing a lighter-than-air ship 15 to enter or leave the hangar and is provided with any convenient type of closure not shown) by means of which the entire ship may be enclosed, if desired, or the hangar could be closed against the Wind while waiting for a ship to approach.

' The hangar itself, instead of being fixedly mounted on a foundation, is mounted on a circular float 16 which rides in a body of liquid 17 in a container 18. The outer rim 19 which constitutes the deck of the float 16 projects over the sides 20 of the container 18. The extreme outer portion 21 of the rim 19 is downturned to enable the drip from the deck to find its way into the gutter 22 from ughich it can be carried off by the drain pipes 2 Around the side 24 of the float 16 is formed a groove 25 in which is placed a cable 26 which passes around the operating drum 2? of a prime mover 28.

On the bottom of the container 18 are placed the supports 29 upon which the float can rest if the level of the liquid 17 is lowered 65 sufliciently. The height of the level of the liquid 17 is regulated by the pump 30 which draws liquid from or returns it to the container 18 through the pipe 31.

In order to prevent the float 16 from engaging the walls of the container 18 there are provided a plurality of rollers 32 which are mounted on the plungers 33 within the housings 34 which,in turn, are mounted in the walls of the container 18. Springs 35 are interposed between the plunger 33 and the housing 34 for the purpose of absorbing any shocks which may be imposed thereon.

It is also desirable to provide the usual antenna 36 and mast 37 for radio equipment which is designed to guide the pilot of the incoming ship, as is now the common practice.

By this construction it will be observed that regardless of the direction of the wind or the direction from which a ship is approach- 85 ing its hangar that it is only necessary to swing the hangar on its floating base until its closed end 12 is turned toward the wind, thus enabling the ship to enter the hangar by flying directly into the wind, as is the common practice.

It will also be observed that should the direction of wind change before the ship is again launched to a position unfavorable for launching it is a very simple matter to rotate the entire hangar until the desired position is attained.

I claim:

1. A hangar for air ships having in combination a revolvable circular float, a hangar mounted on said float, and means for docking said float.
